Description

Technical Field

[0001] The utility model relates to the technical field of jujube beating machines, in particular to a thread-pulling device for a jujube beating machine used for garment processing. Background Art

[0002] A sewing machine is a fully automatic or semi-automatic sewing machine, mostly used for the production of foreign trade clothing. The division of labor of sewing machine operators in the industry includes flat sewing machines, chidori, three-book sewing, sewing and copying. "Sewing" is the name of a job. In the clothing industry, the machines used for sewing are collectively referred to as sewing machines. "Sewing" is very common in clothing, especially in jeans and work clothes, and it mainly plays a role of reinforcement. Sewing thread is very common on our clothes and pants, and its function is to reinforce pockets, cuffs and other easily damaged locations.

[0003] When the sewing machine completes one sewing action, the bottom thread will be automatically cut off, but the thread end on the needle is under the presser foot. When sewing for the second time, the thread end needs to be pushed above the presser foot. In this way, the thread end can be brought under the fabric and woven into the fabric during the next sewing. If the thread end is not pushed above the presser foot, the presser foot will press down and hold the thread end left under the presser foot during the next sewing, leaving thread ends at the start of the seam. However, the traditional method of pushing the thread end above the presser foot is manual. During the operation, the hand may be easily stabbed by the needle, which is dangerous and reduces work efficiency.

[0004] In order to solve the above problems, we have made improvements and proposed a thread-pulling device for a jujube beating machine for clothing processing. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-4 As shown, a thread-pulling device for a tacking machine for garment processing comprises a tacking machine 1, a mounting assembly is arranged at the left end of the tacking machine 1, a bidirectional motor 7 is fixedly connected to the left side of the mounting assembly, a driving gear 8 is fixedly connected to the output end of the bidirectional motor 7, a driven gear 9 is meshedly connected to the bottom end of the driving gear 8, and the driven gear 9 is rotatably connected to the left side of the mounting assembly, a connecting rod 10 is fixedly connected to the left side of the driven gear 9, a thread-pulling plate 11 is fixedly connected to the bottom end of the connecting rod 10, a thread-pulling groove 12 is provided on both the front and rear sides of the thread-pulling plate 11, the length of the connecting rod 10 is slightly greater than the distance from the driven gear 9 to the tip of the needle, and the thread-pulling plate 11 is vertically arranged with the connecting rod 10;

[0023] After the tying machine 1 completes a tying operation, the needle returns to the initial position, and the bidirectional motor 7 works to drive the driving gear 8 to rotate, and the rotating driving gear 8 drives the driven gear 9 to rotate, thereby making the connecting rod 10 swing, and the swinging connecting rod 10 makes the thread plate 11 swing, and then acts on the thread end, and pulls the thread end out from the bottom of the presser foot without manual operation, thereby improving work efficiency and avoiding manual thread pulling and being stabbed by the machine needle.

[0024] Specifically, Figure 1 and Figure 2As shown in the figure, the installation component includes an installation plate 2, and the installation plate 2 is arranged on the left side of the date-stamping bartack machine 1. The top end of the installation plate 2 is provided with an upper clamping plate 3, and the bottom end of the installation plate 2 is provided with a lower clamping plate 6. The right sides of the upper clamping plate 3 and the lower clamping plate 6 both extend to the date-stamping bartack machine 1. Rubber pads are fixedly connected to the bottom end of the upper clamping plate 3 and the top end of the lower clamping plate 6, and a rough structure is arranged at the contact part of the rubber pads and the date-stamping bartack machine 1, increasing the friction force between the upper clamping plate 3 and the lower clamping plate 6 and the date-stamping bartack machine 1, making their connection tighter. A long rod bolt 4 is fixedly connected inside the lower clamping plate 6, and the long rod bolt 4 penetrates through the installation plate 2 to the upper end face of the upper clamping plate 3. A nut 5 is threadedly connected to the top of the long rod bolt 4, and the nut 5 is arranged at the top end of the upper clamping plate 3. The upper clamping plate 3 and the lower clamping plate 6 are installed at the upper and lower ends of the installation plate 2 through the long rod bolt 4 and the nut 5 to form a U-shaped structure, and then installed at the left end of the date-stamping bartack machine 1. Rotate the nut 5 to shorten the distance between the nut 5 and the bottom end of the long rod bolt 4, thereby reducing the distance between the upper clamping plate 3 and the lower clamping plate 6, making them closely fit on the upper and lower sides of the date-stamping bartack machine 1, installing the thread-pulling device on the left side of the date-stamping bartack machine 1, realizing the detachable of the thread-pulling device, making the thread-pulling device applicable to different date-stamping machines, and improving the applicable range.

[0025] Specifically, as Figure 3 and Figure 4 shown in the figure, a pressing arm 15 is arranged at the needle installation part of the date-stamping bartack machine 1. A pressing switch 13 is arranged above the left side of the pressing arm 15, and the pressing switch 13 is fixedly connected to the bottom of the installation component. The output end of the pressing switch 13 is electrically connected to the input end of the bidirectional motor 7. A fixed clamp 14 is fixedly connected to the right end of the pressing arm 15, and the fixed clamp 14 is fixedly installed at the needle installation part of the date-stamping bartack machine 1. The pressing arm 15 is installed at the needle installation part through the fixed clamp 14, so that the pressing arm 15 moves with the movement of the needle. When the date-stamping bartack machine 1 completes a date-stamping operation, the needle resets, causing the pressing arm 15 to reset. During the reset process of the pressing arm 15, it acts on the pressing switch 13, and signals are transmitted to the bidirectional motor 7 through the pressing switch 13 to make it work.

[0026] Working principle: The upper clamping plate 3 and the lower clamping plate 6 are installed at the upper and lower ends of the mounting plate 2 through the long rod bolt 4 and the nut 5 to form a U-shaped structure, and then installed at the left end of the button sewing machine 1. Rotate the nut 5 to shorten the distance between the nut 5 and the bottom end of the long rod bolt 4, thereby reducing the distance between the upper clamping plate 3 and the lower clamping plate 6, making them closely fit on the upper and lower sides of the button sewing machine 1, so that the thread deflecting device is installed on the left side of the button sewing machine 1. After the button sewing machine 1 completes a button sewing operation, the needle returns to the initial position, causing the press arm 15 to reset. During the reset process of the press arm 15, it acts on the push switch 13, and through the push switch 13, a signal is sent to the bidirectional motor 7 to make it work. The bidirectional motor 7 drives the driving gear 8 to rotate when it works, and the rotating driving gear 8 drives the driven gear 9 to rotate, thereby causing the connecting rod 10 to swing. The swinging connecting rod 10 causes the thread deflecting plate 11 to swing, and then acts on the thread end to pull the thread end out from the bottom of the presser foot.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
